Embodiment Construction

[0051]One or more specific embodiments of the present disclosure will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0052]The following describes a system relating to television broadcast signals, and more particularly to broadcast signals as defined for use in the United States. The embodiments described may...

Abstract

New capabilities will allow conventional broadcast transmission to be available to mobile devices. A method is described including receiving a data set, extracting a subset, encoding the subset using a first encoding process, combining the encoded subset with the remaining portion, and encoding the combined data set including the appended subset using a second encoding process. an apparatus is described including means for extracting a subset, means for first encoding, means for combining, and means for second encoding. An apparatus for decoding includes a data identifier receiving a data set and identifying a subset of data, a first decoder decoding the subset using a first decoding process, and a second decoder combining the subset of data with a remaining portion of the data set and decoding the combined data using a second decoding process. A method for decoding is also described.
